This photo of George Osborne discussing childcare tax breaks at a west London nursery is perfect. Contrast Osborne's over-excited face and body language with that of the young boy next to him: the almost-serene expression, the closed eyes, the hunched shoulders and the fists at his temples. It's a strong look.

How would you caption this snap? A couple of suggestions to start:

"Does he ever shut up? I need my nap."

"For God's sake – it's called an 'inside voice' for a reason, George."
